The iniprored hair-Curiel' is used as follows The Curling tube i is pulled iii the direction of the arrow (Fig. 4) so that its upper end gets out of the eye ot' the cross piece if of the holder. the spiral spring being eoinpressed. The eurling` tube is turned in the direction ot' the arrow (Fig. 5) so that it Iets out ot' the U-shaped holder e. A\t'ter the haii' has been wound around the eurling tube n this tube is brought bark to the nornial position in whieh it is niaiiitained b v the action of the spiral springl e. 'lhe heating rod is inserted tl'irough theJ e \'e of the eross pieee of the holder into the upper end ot (hej ein-lingl tube so that it is loeated in the spiral spring if wliieli preients it troni eoniing in eontaet with the wall oi' the euiliirer tube. The upper end of the heatingr rod is serewed into the threaded flange ./Vso that it eaniiot drop out of the tube (Fig. (3).

lt is not neeessar)r that the spiral spring` extends over the eiitire length of the euilingr tube as it nierel \Y serres. on the one. hand to maintain the rui-ling' tube iii the noruial position and. on the other handl to prevent the heating' rod eoniingf in eontiaet with the wall ot' the eul'ling' tube.

fin iniproi'ed hair ellrler eoniprising iii eonibiiiaiion a eurliiig tube. an inwardlY turned internally threaded lang'e at the. outer end of said enrliney tube. a U-shaped holder inouuted in said eurlingr tube. a eross pieve. with an eye at the uiiddle fixed upon the ends otl the U-shaped lioldei said e \'e being designed to reeeii'e the'outer enil of the, eurlini;` tube. a spiral spring loeated in said eurlingr tube Jfor maintainingY the san'ie in its position with its outer end in v4said eye holder` a heating rod to be inserte l into said spiral spring 'tor heatingv the eurlinnr tube. an upper threaded end of said heating' rod adapted to be serewed into the threaded flange of the eurliug;l tube. and zi handle ot insulating niaterial on said upper threaded end of the heating rod` substantially as deserihed and shown and for the purpose Set forth.
